oLosEr VALVE.

Application sied Jane 6,1922. serial No. 566,354.

rhis invention has reference to valve constructions, and more particularly to valve construction of the float control type -employed in vflush tanks.v A.

'fhe primary object et the invention is to provide a valve which will be cushioned in its movement to close oliA the fluid supply, thereby reducing the noise incident to a valve closing, to the minimum.

Another object of the invention is to provide means whereby the stroke ot the valve rod may be adjusted, to cause the valve carried thereby to operate tor closing otlthe supply oiu liuidto the tanlr, at predetermined intervals.

A still further object of the invention is to provide a valve which will automatically cut oli' the passage of fluid therethrough, when one of the pivotvpins or other connecting member becomes broken orl displaced..

With the foregoing and other objects in view which will appear as the description proceedsa the invention resides in the com-V bination and arrangement ot parts and in the details ot construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment ot the invention herein disclosed, may be made within the scopeof what is claimed, without departing from the spirit of the invention.V

Referring to the drawing:

Figure 1 is an elevational view` of a valve mechanism constructedy with the present invention.'

Figure 2 is a vertical sectional view through the same.

Figure 3 is a horizontal sectional view through the upper section.

lelierring to the drawing in detail, the body portion of the valve embodies a lower section 5 and an upper section 6, the sections being formed with Aflanges 7 having openings to accommodate the bolts 8, whereby the sections or the body may be` secured thereto. between the adjacent ends of the sections of the body to insure a fluid-tightconnection therebetween.

The lower section 5 of the body portion is threaded as at '10 to accommodate the nut 11 that cooperates with the shoulder 12 'formed on the section 5 for clamping the valve body within a flushbox.

An inwardly extended flange 13 is formed integral with the lower section of the valve .i

body and dening a valve seat with which A suitable washer 9 is interposed the valve` member 111 carried at, the lower end or" the `valve rod 15 cooperates to cut oill the passage of fluid through the valve body.

The valve member 14 is in the form of a bodyr portion 16 having upwardly extending flanges 17 between which the washer 18 is positioned. of rubber or other suitable materialis vindicated at 19 and is secured to the body portion 16'as'by means oi' the screw 2O that is disposed within a suit-able threaded opening termed in the lower end of the valve rod 1.5.'

Formed integral with the upper Vsection 6 of they body is a downwardly extendingr circular flange 21 adaptedto lit within the A cushioningmember formed the flanged? yto close the upper section or The upper section 6 oit the body hasran opening 22 formed therein, the walls of which opening being threaded to accommodate the plug 23 that has an opening formed therein which opening provides communication between the upper'section 6 and the tanh or box in which the valve body is positioned, to admit fluid to the box. If it is desired to cause the fluid entering the tank to pass through the valve member at a comparatively low rate of speed, the plug 23 may be removed and replaced by a plug having a .smaller opening.

It might be further stated that this plug may be used to restrict the flow or' fluid to the valve member by positioning the same, inthe opening formed in the inwardly extended flange 13. Communicating with the rinterior of the upper section 6 of the body is a pipe 24 that has a right angled extremity 25, through which Huid may pass to the box in which the valve is positioned. An adjusting screw 26 extends into the pipe 24 and Yby means of this adjusting screw, it is obvious that the quantity of fluid passing through the pipe 24 may be regulated to meet the various requirements.l

Pivotally connected to the upper extremity of the valve rod 15 is a linlr member 27 which has pivotal connection with the curved arm 28 as at 29, the curved arm 28 being however pivotally connected to the upper extremity of the valve body.

An arm 30 is pivotally connected to the body portion as at 31, and is ormedwit-h a plurality of spaced `openings 32 to accommodate the pivot pin 33 that provides means ot connection between the arm SO and the link member 34, which also has pivotal connection with the lcurved arm 28 as at 35. The float rod indicated at 36 has connection with the arm 30 so that movement of the. float rod will produce a relative movement of the valve rod l5 through the rods and link member as described.

F rom the foregoing it will be seen that as fluid passes through the valve member and into the box, the float not shown, and which is carried by the float rod 36 moves upwardly moving the valve member carried at the lower end of the valve rod l5 towards its seat to shut otl' the supply of Huid through the valve member.

lVhen the liuid within the box has been released and the rod 36 moved by gravity to the lower portion of the box, the water in the 'upper section 6 of the valve body acts as a cushion to iletard the movement of the valve rod l5 and cause the valvel carried at the end thereof to move to the limit of its upward movement7 gradually.

It it is desired to lengthen the stroke ot the rod l5 to admit a greater quai'itity 'ot tuid, it is only necessary to move the link member 34: to a position adjacent to the outer end of the arm 28.

Having thus described'the invention, what is claimed as new is A valve for use in connection with flush tanlspincluding a body portion having a threaded extremity to be secured within a flush box, and through which water passes to the flush box, a flange extending inwardly from the walls of the body portion and defining a valve seat, an upper section n0rmally supported on the body portion and having a depending flange at the lower end thereof, a valve rod operating through the body portion, a removable valve member supported on one end ot the valve rod, said valve member including an upwardly disposed tapered flange and adapted to cooperate with the irst mentioned tapered flange to prevent the passage o' tluid through the body portion, and a downwardly disposed flange forming a part ot the valve member, a cushioning member positioned within the downwardly disposed flange to move intoy engagement with the valve seat to restrict the passage of Huid through the body portion of the valve, and means for operating the valve.

In testimony that I claim the foregoing as my own, l have hereto atlixed my signature.
